“…e corresponding experimental campaigns were initially projected to be done on the extrados of the chapel vault. is is the most common way to take this kind of measurements in vaults [16], due mainly to two reasons: first, the accessibility is usually easier and auxiliary equipment such as scaffolds or lifting platforms are not necessary; second, some vault intradoses count on decoration, which could be damaged during the fixing of the accelerometers.…”

Today’s society is sensitive to the architectural heritage conservation. This implies to perform works to maintain these buildings and to assure their structural security. In the last years, the structural analysis of historical masonry constructions has experienced a great progress, thanks to the use of techniques based on the study of the dynamic properties of building structures. In this context, changes on the structural health state of a building are one of the elements that can be assessed considering changes on their dynamic properties. This is useful to evaluate the effectiveness of structural interventions on this kind of buildings by analysing these properties before and after it. This paper focuses on the Jura Chapel, in Jerez de la Frontera (Spain). This chapel is part of San Juan de los Caballeros Church and is dated from the 15th century. In 2015 and after the identification of some structural damages in the chapel vault, an intervention was initiated to improve its structural behaviour and to recover its original appearance. The present work reports the evaluation of the effects that this intervention has on the structural health state of the building, using nondestructive techniques based on ambient vibration tests (AVT) and Operational Modal Analysis (OMA). The AVT were performed for both prerestored and restored states and under environmental loads. A discussion about the validity of doing AVT from extrados when a vault presents disconnection between ribs and web is included in the paper. As a result, the first five natural frequency values have increased while the corresponding mode shapes have not changed significantly. This proves a structural health improvement caused by the repairing process without changing the original behaviour of the structure. This work shows OMA capabilities for evaluating the effectiveness of intervention works on the health state of a historical masonry structure.

“…When developing a (FE) models, especially for historic masonry structure, it is possible to define imprecise input parameters that can result in unrealistic models and erroneous solutions [6]. Indefinite references or insufficient material data force researcher to use wide range of data with lower boundary and upper boundary [7]. On this basis it is aimed to predict compressive strength of historical masonry buildings by using material characteristics and physical characteristics.…”

Compressive strength and modulus of elasticity are the key material properties of historical structures to adapt finite element model to obtain correct structural assessment. Generally, modulus of elasticity is adapted by multiplying compressive strength of the material. In this paper, it is aimed to predict compressive strength of historical masonry buildings by using material characteristics and physical characteristics. For this purpose, 21 historical masonry mosques, churches and cathedrals were selected. Unit weight, wall thickness, height of the structure, plan area and modulus of elasticity of the selected 21 historical structures are listed as material characteristics and physical characteristics for using compressive strength prediction. Artificial Neural Network model is used to predict compressive strength of 13 different historical structures. Performance of prediction is verified by using MATLAB among all 34 total historical structures. 0.83 R square is obtained from the prediction model and total prediction performance is obtained from trained data 0.97 and 0.79 from all 34 data by using MATLAB.
